Antisymmetry
The
Antisymmetry
node adds an edge (3D), boundary (2D), or point (2D and 3D) condition that defines an antisymmetry edge, boundary, or point.
Coordinate System Selection
Specify the coordinate system to use for specifying the antisymmetry. See the section
Coordinate System Selection
for
Edge Load
.
Antisymmetry
Select an
Axis to use as anti-symmetry plane normal
to specify the direction of the normal to the symmetry plane in the selected coordinate system.
•
For 2D models, select
1
or
2
for the first or second axis, respectively.
•
For 3D models, select
1
,
2
, or
3
for the first, second, or third axis, respectively.
